Answer:
The reason they don't react is because Elements with full octets are stable, the Elements with no unpaired electrons do not react at all in the decay.
The correct option is this: THE CONCENTRATION OF THE PRODUCTS AND THE REACTANTS DO NOT CHANGE.
A reversible chemical reaction is said to be in equilibrium if the rate of forward reaction is equal to the rate of backward reaction. At this stage, the concentrations of the products and the reactants remain constant, that is, there is no net change in the concentration even though the reacting species are moving between the forward and the backward reaction.
Answer:
The Moon's surface is dominated by igneous rocks. The lunar highlands are formed of anorthosite, an igneous rock predominantly of calcium-rich plagioclase feldspar
Explanation:
Answer:
The condensation of water occurs in Atmosphere.
Explanation:
As we know when water is heated it converts into vapors and vapors on cooling condense back into liquid water. Hence, the water present in Oceans (hydrosphere) on heating evaporates (remember evaporation takes place at any temperature) and move upward into the atmosphere. In atmosphere at high altitude the temperature drops (almost 18 °C) which causes the water vapors to condense hence, resulting in the formation of clouds which on precipitation causes rain fall.
Answer: The chemical formula of a zeolite is Na2. Al2O3. nSiO2 Permutite is an artifical zeolite used for softening of water. Through ion-exchange process, here cation-anion exchange chamber is used to obtain pure water. In calgon's process sodium hexa meta phosphate is used to soften the water.
